A friend of mine has recently had his winchester action rebarreled in 300 wm. At first it was very accurate giving 6 reloads with just neck sizing before having to FL resize. Now accuracy has went to pot and he can only neck size once before having to FL. He also has to set up his FL to contact the shell holder in order to get it to chamber.The loads are not hot. Could this be excessive head space or a prblem with the bolt, he noticed it is making unusualy contact at the very rear of the bolt when lifting the bolt up)? ANy help you can give would be appreciated.
